Fire alarm as used in sunderland royal hospital. This damn thing was tested over a dozen times, whilst i was sitting in the urology department waiting to have the p***taken out of me. I happened to be testing the voice recording capabilities of my sansa clip zip mp3 player, at the time. I'll think you'll agree this is exceptional quality for such a tiny microphone and only minimal background noise removal.
This is an alarm based on what we can hear here in huy, ben-ahin or anywhere near the nuclear power plant of tihange (belgium).

Broadmoor hospital siren test. The broadmoor siren. Every monday morning at ten o'clock the deafening sound of an air-raid siren disturbs the peace over a large area of the leafy commuter belt that is berkshire, uk. The signal sounds the familiar alternating high-low note, followed by a constant all-clear note five minutes later. It's not a re-enactment of the blitz; it's a test of the escape alarm at the local mental hospital, broadmoor.
This is the same sound i recorded 6 years ago, back than i had just a very crappy microphone through my cellphone. Last year i bought an ipad, and i installed hokusai audio editor. This gave me a better way to record in higher quality. Still mono though, but it has less audio artifacts. This alarm is tested once every 3 months all over the swedish towns.
